IMPROVEMENT IN LUBRICATING COMPOUNDS.

Specification forming part of Letters Patent No. 173,840, dated February22, 1876 application filed January 29, 1676.

Providence, in the State of Rhode Island, have invented a new andImproved Compound for V Lubricating Purposes, of which the following isa specification The compound which I have invented is used for oilingthe bearings of machinery, and for all purposes to whichlubricating-oils are now applied. Its price does not exceed that ofsperm oil, and its use, by reason of the peculiarity of its composition,is attended'by far less waste than in the case of other lubricat- Itentirely prevents the overheating of the journals, which is a prolificcause of fires in manut'actories.

My compound is composed of the following ingredients, and insubstantially the followin g proportions 1 dissolve six pounds of boraXin a quantity of water suificient for that purpose. I melt togethereighteen pounds of tallow and four pounds of bees-wax, stirring themwell into each other. When the tallow and bees-wax are thoroughly meltedand mixed, I strain them into seventy-two pounds of parafiine oil, andallow the mixture to cool down to a tempera ture of 80 Fahrenheit. Ithen pour in the dissolved borax, and stir the compound thoroughly untila perfect union of the ingrediportions substantially ents is effected.

This compound can be graded from the lightest to the heaviest grades oflubricatingoils. This is accomplished by slightly chang ing' theproportions of the ingredients. To make a light oil, the quantity of thepar-afiine oil should be increased. To make it a heavy oil, more tallowand bees-wax must be added. The quantities of the tallow and bees-wax,however, should be in relatively the same ratios to each other as abovespecified.

The purpose of the bees-wax is to form a smooth surface on the bearing.The tallow serves to increase the volume or to give 7 body to thepara-dine, and so make the lubricator more durable. The paraffineoil,which is especially the lubricating element of this composition, is, ofitself, too light to adhere Well to the bearing. The hora-X, being analkali, neutralizes the stearine of the tallow, and admits of a perfectunion of all the ingre clients. I therefore claim as a novel and usefulinvention, and desire to secure by Letters Patent- The lubricatingcompound, consisting of par-affine oil, tallow, bees-wax, and dissolvedborax, combined as described, and in the proas specified.
